Intermittent IPv6 Routing Issue
I have set up IPv6 on my local network and it generally works just fine. I get a prefix and traffic routes normally. On occasion, I have noticed that IPv6 traffic does not route back to me, despite my router successfully getting a prefix and a default route. I know that IPv6 traffic is routing outbound just fine, as I can curl or ping6 an IPv6 connected server that I control, and using tcpdump, I can see the request arrive at the server and that the server replies correctly, but I never see the reply come back to the WAN interface of my home connection. All sites, protocols, and ports are affected when it gets into this state. I have noticed that this always coincides when I also get bumped to the 73.95.x.x IPv4 subnet. Once I eventually migrate back to the 24.x.x.x IPv4 subnet, IPv6 starts routing back to my home network and everything works. My prefix does not appear to change.
